COR1 image processed using the Normalizing-Radial-Graded Filter (NRGF) technique as described in Morgan, Habbal, and Woo, "The Depiction of Coronal Structure in White-Light Images", Solar Physics, 236, 263-272, 2006. This technique enhances the contrast of coronagraph images, and makes it easier to see the fainter structures far out from the Sun.
